ARM64 – Pi3 Success – Almost..

Adventures With Linux ™ Posted on by

After more ‘investigation’, I managed to find a working U-Boot for a 64-bit boot of the Raspberry Pi 3, by copying it from the boot directory of this: http://www.tom-yam.or.jp/rpi3/rpi3-arm64-debian-20160414.img.xz found towards the end of the latest 64-bit thread on the Pi Forum: https://www.raspberrypi.org/forums/viewtopic.php?f=72&t=137963&sid=cd15abd8d4dd2a2d5c517f47a3e4f5e4&start=125 .  Thanks to xyinao for putting it all together.. I copied the kernel Image … Continue reading →

Kernel – 4.6-rc5 – OK with (Patched) VMware, and (Patched) NVIDIA..

Adventures With Linux ™ Posted on by

Kernel 4.6-rc5 is out, and brief details of changes from -rc4 are here: http://lkml.iu.edu/hypermail/linux/kernel/1604.3/00178.html Kernel 4.6 seems to have a habit of continuing later-rc breakages with VMware and NVIDIA, compared to previous kernel releases.. The VMware 12 fix for 4.6-rc4 (see http://rglinuxtech.com/?p=1706 ) still works OK with 4.6-rc5, but even the latest NVIDIA driver – 364.19 breaks … Continue reading →

VMware – Later 4.6-rc breaks vmmon and vmnet..

Adventures With Linux ™ Posted on by

Thanks to Justin Palermo, there is a patch for VMware 12 vmmon and vmnet problems he identified with the later Kernel 4.6-rcs.       See comments on my earlier 4.6-rc1 article for details:  http://rglinuxtech.com/?p=1679 I have applied the patch to VMware 12.1.0, on Kernel 4.6-rc4, and VMware now compiles and runs OK..

ARM – Rock2 – Kernel 4.6-rc4 – MMC Swaparound – Bug or Feature?

Adventures With Linux ™ Posted on by

I had been running Kernel 4.6-rc2 on the Radxa Rock2 without any issues, and decided to update to recently-released Kernel 4.6-rc4.. Brief details of changes from -rc3 are here:  http://lkml.iu.edu/hypermail/linux/kernel/1604.2/00610.html The boot failed, and I then compiled/installed 4.6-rc3 to see if that would have been OK, and it was.. I then noticed something odd in the failed … Continue reading →

x86_64 – UP Board – Intel 64-bit, Size of a Pi..

Adventures With Linux ™ Posted on by

Being the pioneer/masochist type (aka ‘early-adopter’..), I was intrigued by the new Intel Atom x5-Z8350-powered UP Board, and now have one on (pre)order.. Basic info, with too much graphics..  http://www.up-board.org/specifications/ Not much info on their forum, yet, but it does have UEFI, so (speculation!) should boot with good old GRUB..  One thing it does not have is … Continue reading →

ARM64 – Pi3 64-Bit Tribulations.. Too Soon for Stability..

Adventures With Linux ™ Posted on by

I had ordered a Raspberry Pi 3 back in March in the hope that it would be a useful exercise in 64-bit on a different chipset..    I was (somewhat) disappointed to find that there was no initial 64-bit support, and indeed that I had been a bit of a pioneer in even running armv7 code on my … Continue reading →

ARM64 – Geekbox – 8-Cores and a UART Gotcha..

Adventures With Linux ™ Posted on by

I recently acquired on of the rather quirky Geekbox ARM64 devices, together with the oddly-named ‘Landingstrip’ expansion board.. http://www.cnx-software.com/2015/11/19/geekbox-is-a-hackable-android-and-linux-tv-box-powered-by-rockchip-rk3368-soc/ http://forum.geekbox.tv/ The similarity in overall design to the ARMv7 Radxa Rock2 will be seen from the photo: If you are ordering one, it is worth getting the USB/UART connector as well, as the 3-pin micro flat-pin connection is … Continue reading →

ARM – Rock2 – Finally an Ethernet Fix that Works..

Adventures With Linux ™ Posted on by

After a lot of searching – and more testing (mostly unsuccessful..) I finally have a set of two patches that fix the Ethernet driver problem with the Rock2 in 4.6-rc1..     The problem is that the stmmac driver is common to several SOC setups, and each maintainer seems to have produced their own version of a fix.. The … Continue reading →
